You don't need the paper gaskets, just the valley pan. I coat the port flanges of the valley pan with copper spray on both sides, and put a bead of grey RTV on the front and back valley pan hold-downs and a small blob at the corners. No RTV around the ports or anywhere except the front/back valley pan hold-downs. No vacuum or oil leaks for me. One thing I did have to do was take some sandpaper and sand all the dried on crud off both the flanges on the heads and on the intake.
